Abstract
Disclosed is an electronic entity having a transponder which includes a body provided with a recess and, inside the recess, a transponder including a mounting supporting an antenna formed by at least one turn running along the contour of the module and a microcircuit, the antenna and microcircuit being connected to one another, plates of conductive material being formed on each of the surfaces facing one another, covering 60-90% of the surface defined by the one or more turns of the antenna, forming a capacitor connected in parallel on the antenna, and the body including an annular metal area, the inner contour of which projects into the plane of the mounting surrounds the mounting and is suitable for concentrating the field lines toward the inside of the turn, the capacitor defining, with the antenna and the microcircuit, a given resonance frequency substantially equal to the frequency of an external reader.
